3d_graph error: Markers showing regex symbols

📊 Plotly Python
1

Hi all,

I’m running into a problem where the plotly → graph_objects → Scatter3D markers are showing the regex symbols. However, it only happens when my app is deployed. See the first image below for the local version, and the second image below for the deployed version. Any idea why this would happen? The only operational difference is that the file is first saved in a GCP storage bucket, then loaded from there into my HTML.

Local environment: WSL Ubuntu-20.04
Deployed environment: GCP Cloud Run, Ubuntu-20.04

Code:

    fig = go.Figure(data=[go.Scatter3d(
        x=df[xdim],
        y=df[ydim],
        z=df[zdim],
        mode='markers',
        marker=dict(
            size=df[sizedim],
            color=df[colordim], 
            colorscale=["#F7B267", "#F25C54"],
            opacity=0.8
        )
    )])

Thanks in advance!
